Other Parts Discussed in Thread: PCM1864
Tool/software:
Hello:
At present, the mic interface channel has been adjusted in sample B. Sample B is only connected to two channels of MIC. The DOUT of PCM1864 in sample B has no output (level 0). TDM CLK and FS signals are input normally. Please help confirm which registers need to be modified? Thanks!!!
The software register configuration is as follows:
i2cdbgr -D /dev/i2c1 -s 0x4a -w -b 2 -o 0x01 -x 0x20
